VALVE.

SPECIFICATION forming part of Letters Patent N 0. 624,821, dated May 9, 1899. Application filed June 27,1898. Serial No. 684,539. (No model.)

To all whom, it may concern:

Be it known that I, OTTO KINNER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Valves, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming passing through said supply-pipe to pass through the radiator.

Figure 1 is a diagrammatic view illustrating two radiators,the water-supply pipe therefor, and the connections from said supplypipe to said radiators. Fig. 2 is a vertical longitudinal sectional view of one of my improved valves. Fig. 3 is a horizontal sectional view taken approximately on the line 3 3 of Fig. 2.

Referring by nu lneralsto the accompanying drawings, 1 indicates the hot-water-supply pipe, and 2 the hot-water radiators.

My improved valve consists of a suitable cast casing, which casing is composed of the vertically-arranged tubular member 3, at the lower end of which is the horizontally-arranged tubular member 4. Formed integral with the upper end of thetubular portion 3 is a hollow head 5, there being a valve-seat 6 formed at the point where said head joins with the tubular member 3 and there being a laterally-projecting flange 7 formed integral with said head 5, which flange is interiorly screw-threaded and adapted to receive one end of the tubular connection 8, that leads to one side of the radiator.

Tapped into the top of the hollow head 5 is a vertically-arranged nipple 9, which is constructed with'a vertically-arranged screwthreaded aperture 10, and the exterior of the end of the nipple 9.

to rest upon the valve-seat 21.

upper end of said nipple 9 is screw-threaded to receive a cap 11, there being suitable packing 12 located within this cap above the upper A valve-stem 13 extends throughout the entire length of the tubular member 3, the hollow head 5, and the nipple 9, the lower end of said valve-stem extending into the horizontally arranged tubular member and being provided with a groove 14. The upper end of said valve-stem 13 is provided with a hand-wheel 15, whereby said valve-stem is actuated.

The valve 16, which is in theform of a disk with abeveled lower surface, is carried by the Valve'stem 13 and is adapted to rest upon the valve-scat 6, and located upon the valve-stem 13 immediately above the valve 16 is a thread 17, which engages in the threads formed in the nipple 9.

One end of the tubular portion t at the lower end of the valve-casing is somewhat longer than the opposite end, and formed integral with said extended end is the upwardlyprojeoting tubular portion 18, the upper end of which is interiorly screw-threaded and adapted to receive a cap 19. Locatedwithin this extended end, immediately beneath said tubular member 18, is a partition 20, in which is formed a horizontally-arranged valve-seat 21. A valve-stem 22 operates through the 22 carries a valve 23, in the form of a disk havingabeveled lower edge, which is adapted A pin 24 is formed integral with and extends upwardly from this valve 23, and an expansive coilspring 25- is located upon said pin, the lower end of said coil-spring resting upon the valve 23, the upper end thereof engaging in a recess formed in the under side of the cap 19. The lower end of the valve-stem 22 is provided with'a groove 26, similar to the groove 14 previously mentioned.

Passing transversely through the horizontally-arranged portion 4; of the valve-casing, at a point midway between the valve-stems 13 and 22, is a pin or screw 26, upon which is pivotally held a short bar 27, the outer ends of which are bifurcated, as indicated by 28, said bifurcated outer' ends engaging in the grooves 14. and 25, formed in the lower ends of the valve-stems. The outer ends of the opening in this partition 20, which valve-stem I horizontally-arranged tubular portion 4 of the valve-casin g are interiorly screw-threadedto receive the ends of the supply-pipe through which the hot water is conveyed to and from the radiators. A tubular connection 29 is made from the end of the radiator opposite the end to which my improved valve is convalve to allow the hot water to pass through the radiator in order to heat the same, the hand-Wheel 15 is manipulated in such a manner as to unseat or raise the valve 16, and by so doing a passage is opened from the supplypipe 1 through the vertical portion 3 of the valve-casing and the tubular connection 8 to the radiator. If desired, the valve may be but partially opened, and when in this position a part of the water from the supply-pipe will pass upwardly through the radiator, the remaining part of said water passing through the horizontally-arranged tubular portion of the valve and the opening that is closed by the valve 23 therein.

When it is desired to cut off the passage through the supply-pipe and to cause all of the water from said supply pipe to pass through the radiator, the valve-stem 13 is so rotated as that it will be elevated, and when the same reaches a certain elevation the bar 27 will have rocked upon its pivot-point andthe valve-stem 22 will have been lowered and the valve 23 will rest upon the valve-seat 21 and close the passage through the valve 20, and consequently through the horizontal portion 4 of the valve-casing, to which the ends of the supply-pipe 1 are connected. This will cause all of the hot water to pass from the supply pipe upwardly through the valve, through the radiator, and back to the supplypipe through the tubular connection 29.

Where ordinary valves are used in the connection from the radiator to the supply-pipe,

all of the water passing through said supplypipe cannot be caused to pass through the radiator. Therefore said radiator cannot be heated quickly nor can the full benefit of all the hot water passing through the pipe beobtained. By the use of a valve of my improved construction these disadvantages and inconveniences are overcome.

My improved valve may not only be used advantageously in hot-water heating systems, but said valve is applicable for use wherever it is desired to throttle, divide, or separate water, air, gas, steam, to. A valve so constructed is simple, inexpensive, does not easily get out of order, and is very efficient in use.

I claim 1. A.' device of the class described, constructed with a vertical member, a horizontally-arranged member at the lower end of the vertical member, said vertical member and said horizontal member each being provided with valve-openings, valve-stems operatin g vertically through said valve-openings, valves carried by said valve-stems, and a rocking bar pivotally held in the horizontal member of the valve-casing, the ends of which bar are bifurcated and engage the lower ends of the valve-stems, substantially as specified.

2. A valve, constructed with a casing having a vertical member and a horizontal member at the lower end of said vertical member, Valve-openings formed in said vertical member and said horizontal member, valves for closing said valve-openings, Vertically-moving valve stems carrying said valves, the lower-ends of which stems are grooved, a pin passing transversely through the horizontal portion of the valve-casing intermediate the lowerends of said valve-stems, and a bar pivotally mounted upon said pin, the ends of which bar are bifurcated to engage in the grooves formed in the lower ends of the valvestems, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

or'ro KINNER.
